I just hate topics like one I just created but I need someone to decide for me. I have Canon 30D, Tokina 10-17 Fisheye, Sigma 30 1.4 and Canon 55-200 4.5-5.6 and want to fullfill empty spaces. I want probably medium tele zoom that is sharp. I don't really need fast lenses because I use a lot of flashes.
My dilemma number one: long telezoom Canon 70-200 f4 NON-IS or Sigma 70-200 2.8. Very similiar price. I want to buy one of these later.
My dilemma number two: medium zoom Tamron 28-75 f2.8 vs Sigma 24-70 f2.8 vs Sigma 17-70, budget 300-500$ I want to spend to these.
I shoot mostly action photos for my website and some magazines.
Thank you for your your time.
